That's pretty much why I refuse to support any game through Patreon. You're essentially paying the dev to drag out development for as long as they possibly can. It's a horrible funding scheme. (Well, for the player, it's great for the developer assuming they can find some suck.. err supporters.)
And it feels REAL scammy when developers only put demo's up on itch or wherever, and you have to subscribe via patreon for the already finished full game. Obviously hoping you forget to unsubscribe.
